Typedef Documentation

dictionary

template<typename key_t , typename value_t >

using xtd::collections::generic::dictionary = typedef std::unordered_map<key_t, value_t, helpers::hasher<key_t>, helpers::equator<key_t>, helpers::allocator<std::pair<const key_t, value_t> >>

#include <xtd.core/include/xtd/collections/generic/dictionary.h>

Represents a collection of keys and values.

Definition

template<typename key_t, typename value_t>
using dictionary = std::unordered_map<key_t, value_t, helpers::hasher<key_t>, helpers::equator<key_t>, helpers::allocator<std::pair<const key_t, value_t>>>;

Header

#include <xtd/collections/dictionary

Namespace

xtd::collections::generic

Library

xtd.core

Remarks

The xtd::collections::generic::dictionary class is same as std::unordered_map.

Examples

The following shows how to use xtd::collections::generic::dictionary.

hash_set

template<typename type_t >

using xtd::collections::generic::hash_set = typedef std::unordered_set<type_t, helpers::hasher<type_t>, helpers::equator<type_t>, helpers::allocator<type_t> >

#include <xtd.core/include/xtd/collections/generic/hash_set.h>

Represents a set of values.

Definition

template<typename type_t>
using hash_set = std::unordered_set<type_t, helpers::hasher<type_t>, helpers::equator<type_t>, helpers::allocator<type_t>>;

Header

#include <xtd/collections/hash_set

Namespace

xtd::collections::generic

Library

xtd.core

Remarks

The xtd::collections::generic::hash_set class is same as std::unordered_set.

key_value_pair

template<typename key_t , typename value_t >

using xtd::collections::generic::key_value_pair = typedef std::pair<key_t, value_t>

#include <xtd.core/include/xtd/collections/generic/key_value_pair.h>

Defines a key/value pair that can be set or retrieved.

template<typename key_t, typename value_t>
using key_value_pair = std::pair<key_t, value_t>;

Header

#include <xtd/collections/key_value_pair>

Namespace

xtd::collections::generic

Library

xtd.core

Remarks

xtd::collections::generic::key_value_pair is an alias of std::pair.

sorted_dictionary

template<typename key_t , typename value_t >

using xtd::collections::generic::sorted_dictionary = typedef std::map<key_t, value_t, helpers::comparer<key_t>, helpers::allocator<std::pair<const key_t, value_t> >>

#include <xtd.core/include/xtd/collections/generic/sorted_dictionary.h>

Represents a collection of key/value pairs that are sorted on the key.

Definition

template<typename key_t, typename value_t>
using sorted_dictionary = std::map<key_t, value_t, helpers::comparer<key_t>, helpers::allocator<std::pair<const key_t, value_t>>>;

Header

#include <xtd/collections/sorted_dictionary

Namespace

xtd::collections::generic

Library

xtd.core

Remarks

The xtd::collections::generic::sorted_dictionary class is same as std::map.

A xtd::collections::generic::sorted_dictionary object maintains a sorted order without affecting performance as elements are inserted and deleted. Duplicate elements are ! allowed. Changing the sort values of existing items is ! supported and may lead to unexpected behavior.

Examples

The following shows how to use xtd::collections::generic::sorted_dictionary.

sorted_set

template<typename type_t >

using xtd::collections::generic::sorted_set = typedef std::set<type_t, helpers::comparer<type_t>, helpers::allocator<type_t> >

#include <xtd.core/include/xtd/collections/generic/sorted_set.h>

Represents a collection of objects that is maintained in sorted order.

Definition

template<typename type_t>
using sorted_set = std::set<type_t, helpers::comparer<type_t>, helpers::allocator<type_t>>;

Header

#include <xtd/collections/sorted_set

Namespace

xtd::collections::generic

Library

xtd.core

Remarks

The xtd::collections::generic::sorted_set class is same as std::set.

A xtd::collections::generic::sorted_set object maintains a sorted order without affecting performance as elements are inserted and deleted. Duplicate elements are ! allowed. Changing the sort values of existing items is ! supported and may lead to unexpected behavior.

Examples

The following example demonstrates how to merge two disparate sets. This example creates two xtd::collections::generic::sorted_set objects, and populates them with even and odd numbers, respectively. A third xtd::collections::generic::sorted_set object is created from the set that contains the even numbers. The example then calls the UnionWith method, which adds the odd number set to the third set.
